FIELD: heating.
SUBSTANCE: proposed multi use plate of the plate heat exchanger contains the following: the extreme and middle parts, lying in the first plane; the rib, mating these parts, the middle of which lies in the second plane parallel to the first; the first and the second pairs from the first and the second holes same in size on the opposite sides of the middle part. These pairs of holes are positioned mirror-wise relatively to the transverse axis, passing in the first or the second plane equidistantly between the pairs of holes; at that the first and the second hole in each of these pairs of holes are formed in the sections of the middle part, lying respectively in the first and the second planes; the entire space of the middle part between the sections with holes is occupied by alternating recesses and protruberances, at that the recesses bottom and the protuberances tops are lying respectively in the first and the second planes. The package assembly of such plates consists in consequent plates packing one by one with the similar planes with the rotation of each even or each odd plate by 180° relatively to the transverse axis, after that provide the plates welding in the contact places of their similar planes. The turbulizing elements can be placed in some of the forming cells, that allows to change the hydro-gasdynamic and heat-mass exchange characteristics of the working channels.
EFFECT: operating means range expansion.
